Description

Technical Field

[0001] The utility model relates to the technical field of road rollers, and more specifically, the utility model relates to a steel wheel scraper of a vibratory road roller. Background Art

[0002] A road roller, also known as a soil compactor, is a device for road construction. Road rollers belong to the category of road equipment in construction machinery. It can roll sandy, semi-viscous and viscous soils, subgrade stabilized soils and asphalt concrete pavement layers. With the gravity of the machine itself, the road roller is suitable for various compaction operations, causing permanent deformation and compaction of the compacted layer.

[0003] When operators perform filling and compaction operations, they often use vibratory road rollers to compact the pavement surface. Existing vibratory road rollers are often equipped with scrapers in front of the road roller to push and clean the debris on the uncompacted road surface. However, the widths of these scrapers are often fixed and cannot be telescoped according to the usage requirements. When there is too much debris on the road surface, the debris in front of the scraper will be squeezed against each other, and then the debris will move to both sides of the scraper, reducing the cleaning effect and affecting the road compaction effect of the road roller, which brings inconvenience to the operation of the operator. Therefore, it needs to be improved. Summary of the Utility Model

The other end of the threaded rod is movably connected to a stop block, and the bottom end of the stop block is fixedly connected to the top end of the fixed bracket.

[0016] As a preferred technical solution of the present utility model, a square block is threadedly sleeved on the outer surface of the threaded rod. The bottom end of the square block is movably connected to the top end of the fixed bracket. A moving block is fixedly installed at the bottom end of the square block.

[0019] 1. The utility model realizes the function of expanding and contracting the shovel blade according to the usage requirements and improves the overall applicability of the main shovel blade by setting a push rod, a moving rod, a rotating rod and a driving motor. When the driving motor operates, the rotating shaft will drive the rotating rod to rotate. At this time, the two moving rods will move under the drive of both ends of the rotating rod. Then, the other ends of the two moving rods will drive the two push rods to move respectively. Since the inner parts of the tops on both left and right sides of the main shovel blade are movably connected to the outer surfaces of the tops of the two telescopic shovel blades respectively, the movement of the two telescopic shovel blades is limited. At this time, the two telescopic shovel blades will move away from each other under the drive of the two push rods.

Since the bottoms of the two square blocks are in contact with the top of the fixed bracket, the two square blocks will move away from each other under the drive of the two threaded rods. Then, the two square blocks will drive the two movable shafts to move through the two moving blocks and the two first hinge blocks. At this time, the other ends of the two movable shafts will release the pulling effect on the two second hinge blocks during the movement. Subsequently, the whole cross beam will move under the influence of gravity. Due to the limiting effect of the two limiting grooves on the two lifting blocks, the whole cross beam will move downward.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0028] As Figures 1 to 5 shown, the present invention provides a vibrating roller steel wheel scraper, including:

[0029] The main scraper 1, and a cross beam 2 is fixedly installed at the top end of the front surface of the main scraper 1;

[0030] The telescopic mechanism is arranged inside the top ends on the left and right sides of the main scraper 1;

[0031] The driving mechanism is arranged at the bottom end of the cross beam 2;

[0032] Among them, the telescopic mechanism includes telescopic scrapers 3. The number of the telescopic scrapers 3 is two. The backs of the two telescopic scrapers 3 are movably connected to the front surface of the main scraper 1. The outer surfaces of the top ends of the two telescopic scrapers 3 are respectively movably connected to the inside of the top ends on the left and right sides of the main scraper 1. Push rods 4 are fixedly installed on the opposite sides of the two telescopic scrapers 3. The backs of the push rods 4 are movably connected to the front surface of the main scraper 1. The outer surface of the other end of the front surface of the push rod 4 is movably sleeved with a moving rod 5, and the outer surface of the other end of the moving rod 5 is movably sleeved with a rotating rod 6.

[0033] Since the outer surfaces of the top ends of the two telescopic scrapers 3 are respectively movably connected to the inside of the top ends on the left and right sides of the main scraper 1, the two telescopic scrapers 3 can only move left and right. When the rotating rod 6 rotates, at this time, the two ends of the rotating rod 6 will drive the two moving rods 5 to move. Then, the other ends of the two moving rods 5 will respectively drive the two push rods 4 to move. At this time, the opposite ends of the two push rods 4 will drive the two telescopic scrapers 3 to move away from each other.

[0034] Among them, the driving mechanism includes:

[0035] The motor fixing frame 7, and the top end of the motor fixing frame 7 is fixedly connected to the bottom end of the cross beam 2;

[0036] The driving motor 8, the back surface of the driving motor 8 is fixedly connected to the bottom end of the front surface of the motor fixing frame 7. The other end of the output shaft of the driving motor 8 is fixedly sleeved with a rotating shaft 9, and the other end of the rotating shaft 9 penetrates through the front surface of the motor fixing frame 7 and is fixedly sleeved with the inside of the center of the rotating rod 6.

[0037] When the driving motor 8 operates, at this time, the rotating shaft 9 will drive the rotating rod 6 to rotate.

[0038] Among them, fixed brackets 10 are movably connected to the left and right sides of the cross beam 2. Horizontal grooves 11 are provided on the left and right sides of the top ends of the fixed brackets 10, limit grooves 12 are provided at the bottom ends of the left and right sides of the fixed brackets 10, and fixed blocks 22 are fixedly installed on the left and right sides of the front surface of the fixed brackets 10.

[0039] Due to the design of the two limit grooves 12, the object located inside them will be limited, enabling it to move only up and down.

[0040] Among them, lifting blocks 13 are movably connected inside the limit grooves 12. The number of lifting blocks 13 is two, and the opposite ends of the two lifting blocks 13 are fixedly connected to the left and right sides of the cross beam 2 respectively.

[0041] Due to the limiting effect of the two limit grooves 12, the two lifting blocks 13 can only move up and down, and further the entire cross beam 2 can only move up and down.

[0042] Among them, a double-shaft motor 14 is fixedly installed at the top end of the fixed bracket 10. The other end of the output shaft of the double-shaft motor 14 is fixedly sleeved with a threaded rod 15. The other end of the threaded rod 15 is movably connected to a stop block 16, and the bottom end of the stop block 16 is fixedly connected to the top end of the fixed bracket 10.

[0043] When the double-shaft motor 14 operates, the two threaded rods 15 will rotate at this time.

[0044] Among them, a square block 17 is threadedly sleeved on the outer surface of the threaded rod 15. The bottom end of the square block 17 is movably connected to the top end of the fixed bracket 10. A moving block 18 is fixedly installed at the bottom end of the square block 17. The outer surface of the moving block 18 is movably connected to the inside of the horizontal groove 11, and the bottom end of the moving block 18 extends into the fixed bracket 10 through the horizontal groove 11.

[0045] Since the bottom ends of the two square blocks 17 are in contact with the top end of the main shovel 1, when the two threaded rods 15 rotate, the two threaded rods 15 will drive the two square blocks 17 and the two moving blocks 18 to move away from each other at this time.

[0046] Among them, a first hinge block 19 is fixedly installed at the bottom end of the moving block 18. A movable shaft 20 is hinged inside the first hinge block 19. The other end of the movable shaft 20 is hinged to a second hinge block 21, and the bottom end of the second hinge block 21 is fixedly connected to the top end of the cross beam 2.

[0047] When the two moving blocks 18 drive the two first hinge blocks 19 to move away from each other, at this time, the two movable shafts 20 will move under the drive of the two first hinge blocks 19. At this time, the other ends of the two movable shafts 20 will release the pulling effect on the two second hinge blocks 21 during the movement. Immediately afterwards, the two second hinge blocks 21 and the cross beam 2 as a whole will move downward under the action of gravity.

[0048] The working principle and usage process of the present utility model:

[0049] First, the operator starts the driving motor 8. At this time, the rotating shaft 9 will rotate. Immediately afterwards, the rotating rod 6 will rotate under the drive of the rotating shaft 9. At this time, the two ends of the rotating rod 6 will drive the two moving rods 5 to move respectively during the rotation. Subsequently, the other ends of the two moving rods 5 will respectively squeeze and push the two push rods 4 to make them move. At this time, the two telescopic shovels 3 will move under the drive of the two push rods 4. Since the outer surfaces of the tops of the two telescopic shovels 3 are respectively movably connected to the interiors of the tops on the left and right sides of the main shovel 1, the interiors of the tops on the left and right sides of the main shovel 1 will limit the movement of the two telescopic shovels 3. At this time, the two telescopic shovels 3 will move away from each other, thus realizing the function of telescoping the shovel according to the usage requirements.

[0050] Subsequently, the operator starts the double-shaft motor 14. At this time, the two threaded rods 15 will rotate. At this time, the two threaded rods 15 will drive the two square blocks 17 to move respectively during the rotation. Since the bottoms of the two square blocks 17 are respectively in contact with the tops of the fixed brackets 10, at this time, the two square blocks 17 will move away from each other. Immediately afterwards, the two square blocks 17 will respectively drive the two moving blocks 18 to move away from each other along the interiors of the two transverse grooves 11. At this time, the two first hinge blocks 19 will move away from each other under the drive of the two moving blocks 18. Subsequently, the two first hinge blocks 19 will respectively drive the two movable shafts 20 to move. At this time, the other ends of the two movable shafts 20 will release the pulling and supporting effect on the two second hinge blocks 21. At this time, the two second hinge blocks 21 and the cross beam 2 as a whole will move under the influence of gravity. Due to the design of the interiors of the two limiting grooves 12, the movement of the two lifting blocks 13 will be limited, enabling them to move only up and down. At this time, the cross beam 2 as a whole will move downward, thus realizing the function of adjusting the overall height of the main shovel 1 according to the usage requirements.
